Installation Guide

• Mount the positioner securely on the actuator using the standard mounting interface.
• Connect the air supply to the G 1/4 or 1/4-18 NPT pneumatic ports.
• Wire the 4–20 mA signal to the screw terminals and observe the maximum wire sizes.
• Use the 1/2-14 NPT or M20x1.5 cable entries for electrical connections.
• Do not expose the terminals to strain during installation or maintenance.
• Verify the fail-freeze safe position before putting the valve into service.
